In the Report of the Dominion Entomologist for 1901 a notice was given of this insect, the moth of which has for some years at Ottawa been one of the commonest species of the genus found flying during the summer. Any species as abundant as this is must be injurious, should the caterpillars at any time attack a cultivated crop. The larvæ have occasionally been found in vegetable gardens, around peas and beet root, but no injury as yet has been noticed. The finding of a cluster of eggs last year by Mr. Gibson gave on opportunity of studying the life-histroy, which is herewith submitted.

Dactylopius Wheeleri,n. sp.– ♀ flesh colour, covered with a white, fluffy material, elongate oval,1¾ mm. long, 1 broad ½ high, convex, very flat beneath. Segmentation distinct. Boiled in potash, they turn brown; transferred to cold water, the internal juice becomes colourless. Pressed under cover-glass, the skin is colourless, with several long hairs anteriorly and on the caudal region above the anal ring and caudal tubercles. Anal ring normal, with six stout bristles. Caudal tubercles very prominent, with two long bristles 120 and 260 μ long. Legs stout, front leg coxa 140. Femur and trochanter 220. Tibia 148. Tarsus 100 μ long. Claw thin, sharp, with a distinct tooth near the end. Tibia and tarsus have several short hairs. Digitules of tarsus and claw very small. Labium small. Rostral loop exceedingly long.

The globose or rounded head, which is nevcr flat, oblong, and the difference in the antennæ, the antennæ in males being 10-jointed in the females 13-jointed, readiiy separate the subfamily from the Bethylinæ. The group comes quite close to the Dryininæ, but in the latter the head is transverse or subquadrate, never rounded, while the antennæ are 10-jointed in both sexes.

The genus Olixon, Cameron, originally described as a Braconid, belongs here, without much doubt, I think, judging from the description and the figure. Cameron say" “I am unable to point out the natural position of this curious genus. The elongated fore legs give it a look of a Bethylid, to which, indeed, it bears a general resemblance,; but I feel inclined to regard it as a true Braconid.” I have not seen a specimen of this genus, but Mr. Cameron's figure and description clearly show that it belongs here; the thickened fore femora are characteristic of the group.

Culex atropalpus, new species.

♀. Black the halteres, apices of coxæ, and bases and under side of femora, except toward the apex, yellowish white; scales of palpi black, occiput covered with board, appressed whitish scales and with a patch of black ones near the middle of each side, the middle of the upper side covered with narrow yellowish scales, the upright forked scales yellow; scales of mesonotum golden yellow and with an median vitta of black ones; scales of abdomen purplish black, and with a narrow fascia of whitish ones at the bases of the segments, becoming much broader on the venter; scales of legs black, those at base and on under side of femora, except toward the apex, also to extreme apices of femora, both ends of tibiæ and of the tarsal joints, except the last two and apex of the third on the front and middle tarsi, white those on last joint of hind tarsi wholly white; claws of front and middle tarsi toothed, those of the hind ones simple; wings hyaline, lateral scales of the veins long and narrow, first submarginal cell slightly over twice as long as its petiole.

The specimens on which this description is based are in the collections of the University of Nebraska and of the author. I owe especial acknowledgments to Mr. J. C. Crawfrod, Jr., for specimens and field observations, andto professor Bruner for directing my work.A sixteen-power glass was used in determining characters.

Myodites solidaginis, n. sp. – Female: Length, 7.9 mm. Head depressed, finely and evenly punctate, clad with dense yellowish-white, perpendicular pubescence; antennæ pectinate, ten-jointed, pubescent, very finely punctate, third joint with base of tooth yellowish; vertex between antennæ elevated; mandibles with the exterior side finely punctate, densely pubescent, grooved, in front and on interior sides shining glabrous. Thorax densely punctate, with median groove, but becoming mesially carinate behind the centre, clad with dense, upright, yellowish-white pubescence.

Peridroma canities n. sp. – Form and markings of the Texan P. annexa, but of a different, dusty gray, colour and a little shorter winged. Primaries dusty gray, with a slight dusky shading along costa, against which the pale dots, marking inception of transverse lines, are relieved. T.p. line tolerably distinct, indentate interspaceally, with included pale shade. Veins marked with fuscous. T. a. line double, with a strong outward inflection above internal margin. Claviform blunt, filled in with fuscous. Orbicular with central dot. Reniform moderate,filled in with fuscous. Cell slightly darker shaded. Marking inconspicuous, concolorous. Hind wings (♀) white.
